XLT Hitachi X200 - Manual (Page 70)

Wire the Inverter Output to Motor
Step 7: The process of motor selection is beyond the scope of this manual. However, it
must be an AC induction motor with three phases. It should also come with a chassis
ground lug. If the motor does not have three power input leads, stop the installation and
verify the motor type. Other guidelines for wiring the motor include:
x Use an inverter-grade motor for maximum motor life (1600V insulation).
x For standard motors, use the AC reactor accessory if the wiring between the
inverter and motor exceeds 10 meters in length.
Simply connect the mot or to the terminals
[U/T1], [V/T2], and [W/T3] as shown to the
right. This is a good time to connect the
chassis ground lug on the drive as well. The
motor chassis ground must also connect to
the same point. Use a star ground (single-
point) arrangement, and never daisy-chain
the grounds (point-to-point).
x Check the mechanical integrity of each
wire crimp and terminal connection.
x Replace the housing partition that
covers access to the power connections.
CAUTION: Power terminal assignment is different compared to old models such as L100, L200
series, etc,. Pay attention when wiring the power cable
Logic Control Wiring
After completing the initial installation and powerup test in this chapter, you may need
to wire the logic signal connector for your application. For new inverter
users/applications, we highly recommend that you first complete the powerup test in
this chapter without adding any logic control wiring. Then you will be ready to set the
required parameters for logic control as covered in Chapter 4, Operations and
Monitoring.
